The verified range covers seven trip-indicator variants from 25 A through 100 A, all using the gR characteristic and 36x127 size. The series has a maximum interrupting rating of 100 kA at rated voltage with L\/R = 20 ms. Mersen identifies these fuses as extremely fast acting and current limiting, with very low I²t. This page consolidates the manufacturer-documented range so procurement and maintenance teams can compare exact catalog numbers, Item numbers, current ratings, and watt loss before RFQ or replacement review.\u003c\/p\u003e\n\n\u003ch2\u003eProtistor 36x127 gR (GRB\/C) Series Overview\u003c\/h2\u003e\n\u003cp\u003eThe Protistor 36x127 gR range is designed for semiconductor protection in DC circuits. Mersen states that these fuses provide lower I²t to help minimize damage to protected components during short circuits, along with lower watt loss and tested cycling capability. All models covered here are rated 1000 VDC and use the same 36x127 cylindrical format with trip-indicator. Rated current and associated watt loss are the principal documented differences between the seven catalog-number variants.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; table-layout: fixed; border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 13px; margin-top: 16px; font-family: sans-serif;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"width: 32%; padding: 8px 10px; background-color: #f2f2f2; font-weight: bold; color: #333; text-align: left; vertical-align: top; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eSpecification\u003c\/th\u003e\n\u003cth style=\"width: 68%; padding: 8px 10px; background-color: #f2f2f2; font-weight: bold; color: #333; text-align: left; vertical-align: top; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eSeries Data\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eProduct type\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eIEC high-speed cylindrical fuse-links for DC semiconductor protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eRated voltage DC\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003e1000 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eRated current range\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003e25-100 A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eSpeed \/ characteristic\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003egR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eProduct size\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003e36x127\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eMaximum interrupting rating IR\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003e100 kA at rated voltage, L\/R = 20 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eConfiguration\u003c\/td\u003e\n\u003ctd style=\"padding: 8px 10px; color: #555; line-height: 1.5; vertical-align: top; border-bottom: 1px solid #e0e0e0; white-space: normal; overflow-wrap: anywhere; word-break: normal;\"\u003eWith trip-indicator\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical data reference:\u003c\/strong\u003e Mersen Protistor® size 36x127 gR (GRB\/C) 1000VDC, document DS-PROTISTOR-36x127-gR-1000-01-0726-EN.\u003c\/p\u003e\n\n\u003ch2\u003eProtistor 36x127 gR (GRB\/C) Model Selection\u003c\/h2\u003e\n\u003cp\u003eThe verified range provides seven rated-current options: 25 A, 32 A, 40 A, 50 A, 63 A, 80 A, and 100 A.
