OEM Industries CNL 50A Circuit Protector DC48V AC125V RQD-1

SKU CH-60JM-S1YCK

A 50 amp circuit protector rated for 48 V DC and 125 V AC applications

  • Amperage50
  • Product typeCircuit Protectors
  • Rated for 50 A continuous protection
  • Dual-voltage design covers DC 48 V and AC 125 V
  • CNL series breaker fits standard fuse blocks
  • Fast-acting thermal trip limits fault energy
  • New condition ensures full factory performance

Purpose & Audience

The OEM Industries CNL 50A circuit protector is a 50 amp fuse rated for DC 48V and AC 125V applications. It is intended for automotive and generator electrical systems that require this specific current and voltage rating.

Fit & Exclusions

This device suits installations needing a CNL series 50A protector at the stated voltages. It will not meet the needs of circuits requiring a higher or lower amperage rating, a different voltage class, or an alternative fuse form factor.

Installation & Common Issues

Installation consists of placing the fuse into a compatible CNL holder or block. The most frequent issue is selecting a fuse with incorrect amp or voltage ratings for the circuit, which can lead to nuisance blowing or insufficient protection.

Questions about this item

What voltage-rated circuit must I already have in place for the 50 A CNL protector to function?

The protector is rated for DC 48 V or AC 125 V circuits, so your existing wiring and supply must match one of those voltages.

Will the 50 A CNL protector coordinate with a lower-rated fuse already in the same DC 48 V branch?

Coordination depends on the time-current curves of both devices; the CNL 50 A will carry up to 50 A continuously before opening, so a smaller fuse upstream may blow first.

How can I verify the CNL 50 A protector is operating correctly after installation?

Apply a known load below 50 A and confirm the circuit remains closed, then use a calibrated current source to exceed 50 A and observe the protector opening the circuit.
