HySecurity MX001096, CIRCUIT BREAKER, 42 VDC, 150 A
The HySecurity MX001096 circuit breaker is a 42VDC, 150A high-current DC breaker used in select HySecurity power-supply applications. Official HySecurity catalog data identifies the MX001096 as the 150A DC circuit breaker for 200 UPS / 444DX power supply references, while separate parts are used for 60A and 120A DC applications. This makes amperage matching critical. A circuit breaker is not a performance upgrade part; it is a protective device selected for a specific conductor size, power supply output, and load design. Replacing a breaker with the wrong rating can remove protection from the circuit or cause nuisance shutdowns. Order MX001096 only when the power-supply diagram lists the 42VDC 150A breaker.

Technician Note
If the breaker trips, diagnose the load and wiring before replacing the breaker. A breaker that opens may be doing its job.
Before Ordering Checklist
- Confirm the power supply calls for MX001096
- Verify 42VDC and 150A rating
- Compare terminal layout and mounting style to the original breaker
- Check for shorted wiring, failed power supply components, or motor/load issues
- Do not increase breaker amperage to stop nuisance trips
Professional Advisory
High-current DC circuits can arc and create severe hazards. Do not bypass this breaker or replace it with a non-matching rating.
Important Ordering Warnings
- Do not substitute 60A, 120A, and 150A breakers
- Do not bypass the breaker
- Repeated tripping requires diagnosis before returning the gate to service
Product Questions and Answers
What is the rating of MX001096?
MX001096 is a 42VDC, 150A circuit breaker.
Where is MX001096 used?
It is used in select HySecurity DC power supply applications, including 200 UPS / 444DX style references where specified.
