The HongMan HMEV7-series high-performance bolt-on-type fuse is a dedicated DC protective device engineered for new-energy vehicle battery systems, energy-storage battery assemblies and high-voltage DC distribution hardware. Equipped with a sophisticated arc-quenching ceramic housing and accurately calibrated melting-element construction, this component delivers consistent, dependable short-circuit and overcurrent safeguarding for high-amperage DC circuits, while retaining steady operational performance amid prolonged heavy-duty loads and high-voltage operating environments.

Rated for 700 V DC and supporting a maximum DC operating voltage of 750 V, this fuse features a 50 kA rated interrupting capacity. It is capable of tripping instantaneously in the event of violent short-circuit faults, thereby preventing permanent damage to batteries, inverters and power modules. Thanks to its aR ultra-rapid breaking performance, it serves as a well-suited protective option for high-voltage, high-power DC electrical loops.

Dimensional Data for HMEV7 Fuse Link:

1.Constructed with high-strength melamine insulating housing, this fuse withstands high temperature, mechanical impact and arc abrasion. It effectively confines internal arc energy upon fusing, removes fire hazards from high-voltage high-current circuits and secures overall power-system operation.

2.Boasting aR ultra-quick interrupting capability, it cuts off fault overcurrent within milliseconds once short-circuit occurs. It fits lithium-ion battery pack protection requirements well and prevents thermal runaway risks, making it a preferred part for cell-level fuse protection solutions.

3.It adopts standard bolt-mount configuration, featuring dual-sided flat copper terminals with oval mounting apertures. This design facilitates wiring and assembly, keeps contact resistance low, minimizes heat buildup during continuous heavy-current conduction, and supports broad compatibility with standard mounting brackets of equivalent specifications.

4.Designed for superior interrupting performance with 50 kA short-circuit breaking rating, the fuse works reliably for high-power energy storage and NEV high-voltage DC circuits. It maintains dependable protection under severe fault scenarios and handles diverse complex operating conditions.

5.Possessing official safety approvals, the product conforms to national low-voltage fuse specifications. It has passed rigorous temperature-rise, breaking-capacity and aging tests, suitable for large-scale commercial-industrial deployment and satisfies certification criteria from major new-energy and energy-storage sectors.

This heavy-duty DC Battery Fuse is widely used in multiple high-voltage and high-current DC scenarios, and is also the core protection component for DC 700V Fuse application solutions in various industries:
