Square D PCF2536 Molded Case Circuit Breaker

For facilities upgrading their electrical infrastructure, the legacy PCF2536 is typically replaced by the Square D RLF36250U31A. Because the newer model utilizes an R-frame footprint, a retrofit kit is required to adapt it to existing switchboards or motor control centers.

This 2500A P-frame breaker is specifically designed to bolt directly into Square D switchboards and motor control centers. It is engineered to handle heavy industrial loads within these high-capacity distribution systems.

The breaker utilizes a unit-mount, bolt-on connection type. This bolted configuration provides the high clamping force necessary to safely conduct up to 2500 amps continuously without excessive heat generation at the terminals.

It utilizes a thermal magnetic trip unit with LI (Long-Time and Instantaneous) functions. The thermal overload protection is fixed, while the magnetic instantaneous trip is adjustable, allowing panel builders to fine-tune the short-circuit protection curve based on the specific load requirements.

No, terminal lugs are sold separately for this model. Electricians must source the appropriate lug kits based on the specific wire size and conductor material used in their installation.

This molded case circuit breaker is UL listed and CSA approved. It meets UL 489 and NEMA AB 1 standards, ensuring safe operation and reliable fault interruption in commercial and industrial environments.
