The TBC TSF-363 Switch Fuse is a robust 3-pole, 63A switching and protection device engineered for demanding low-voltage power distribution applications. Combining reliable load isolation with high-performance fuse protection in a compact DIN-rail format, this switch fuse delivers 50kA breaking capacity and is ideal for industrial control panels, main distribution boards, and commercial electrical installations where safety and reliability are paramount.
The TSF-363 Switch Fuse from TBC (CURRENT ENERGY (M) SDN. BHD.) represents a professional-grade solution for low-voltage power distribution systems requiring both switching capability and overcurrent protection. This device integrates a manual isolation switch with fuse protection technology, providing a dual-function unit that simplifies installation while enhancing system safety.
Designed for 3-phase AC networks operating at 240/415V and 50/60Hz, the TSF-363 handles rated currents up to 63A with an impressive 50kA breaking capacity. The use of Neozed DO2 fuse links ensures reliable and predictable protection characteristics, while the clear isolation function allows maintenance personnel to safely de-energize downstream circuits.
Built to withstand challenging environmental conditions, this switch fuse operates reliably across a temperature range of –35°C to +70°C and tolerates relative humidity up to 95%. Its compact dimensions (90mm H × 81mm W × 78mm D) and standard DIN-rail mounting make it easy to integrate into existing distribution boards and control panels.
Compliance with IEC 60947-3 standards and CE marking demonstrate the TSF-363's adherence to international safety and performance requirements, making it suitable for a wide range of industrial and commercial electrical installations worldwide.
Electrical Characteristics:
The TSF-363 is rated for 63A continuous current operation on 3-phase AC systems with rated operational voltage (Ue) of 240/415V at 50/60Hz frequency. The device provides a breaking capacity of 50kA, ensuring effective protection against high-magnitude fault currents. It utilizes Neozed DO2 type fuse links, which are industry-standard components known for their reliable performance and easy replacement.
Mechanical Design:
Constructed for DIN-rail mounting, the switch fuse features compact dimensions of 90mm height, 81mm width, and 78mm depth. The device is engineered for 5,000 mechanical operations, providing long-term reliability in switching applications. The manual operating mechanism provides clear ON/OFF indication and positive isolation for maintenance safety.
Environmental Performance:
With an operating temperature range of –35°C to +70°C and tolerance for relative humidity from 0 to 95%, the TSF-363 is suitable for installation in harsh industrial environments. The IP20 degree of protection ensures safety against solid objects greater than 12.5mm while being appropriate for indoor enclosure mounting.
Standards Compliance:
The TSF-363 is manufactured in accordance with IEC 60947-3 (Low-voltage switchgear and controlgear – Part 3: Switches, disconnectors, switch-disconnectors and fuse-combination units) and carries CE marking, confirming conformity with applicable European directives for safety and electromagnetic compatibility.
