Overview
The Bussmann H25060-3C is an industrial-grade 3-pole fuse block holder designed for Class H fuses in 250VAC control systems. This H250 series fuse block provides reliable overcurrent protection in industrial control circuits, panel applications, and AC/DC control systems. Built with thermoplastic construction and UL-certified design, the H25060-3C delivers durability and safety-rated electrical protection for equipment up to 60A.
Key Features
- 3-pole configuration — accommodates three independent Class H fuses for multi-circuit protection
- 60A rated — supports fuse capacities from 31–60A (Class H NON and REN fuses)
- 250VAC/125VDC — suitable for 250VAC primary applications with 125VDC auxiliary control circuits
- Box lug terminal — accepts copper wire 14–2 AWG and aluminum wire 8–2 AWG for secure screw-lug connections
- Bolt-down mount — chassis or DIN rail mounting for compact control panel layouts
- UL/CE/CSA certified — meets industry standards (UL 248, CSA File 47235) with 10kA RMS short-circuit withstand rating
