What Is a Molded Case Circuit Breaker (MCCB)?
A molded case circuit breaker (MCCB) is an electrical protection device that automatically interrupts a circuit when it detects an overload or short circuit condition. Unlike fuses, MCCBs can be reset and reused. The Square D FH36035 uses a thermal magnetic trip mechanism — thermal elements protect against sustained overloads, while the magnetic element reacts instantly to high-magnitude fault currents.
What Is I-Line Style Plug-In?
I-Line is a Square D proprietary bus connection system found in Schneider Electric's I-Line panelboards and switchboards. The plug-in design allows circuit breakers to be connected directly to the bus bar without additional wiring, reducing installation time and improving reliability in high-amperage distribution environments.
Typical Applications
- Industrial manufacturing facilities
- Commercial electrical distribution panels
- Three-phase motor branch circuit protection
- Feeder and branch circuit protection in I-Line switchboards
- HVAC, pumps, and compressor systems
- Replacement for existing FH-series breakers in Square D panels
