Molded Case Circuit Breaker Locking Device 29370, Compact Accessory with Overload Protection

Compact, reliable circuit breakers designed to protect electrical circuits from overloads and short circuits while keeping installation and maintenance straightforward. Key benefits Prevents damage and downtime by interrupting overcurrent and shortcircuit faults before they cause wiring or equipment stress. Fast, predictable trip performance that isolates faulted circuits quickly to minimize impact on the rest of the system. Spacesaving design fits standard distribution panels and DINrail mount enclosures for efficient use of cabinet space. Durable construction and robust contact materials reduce wear from frequent switching and improve longterm reliability. What it does and how it solves problems Overload protection: thermal trip element responds to sustained overcurrent conditions, preventing conductor overheating and cable damage. Shortcircuit protection: magnetic trip element reacts instantly to fault currents to interrupt dangerous fault paths and limit equipment exposure. Manual operation and reset: easily switch circuits on and off for maintenance or troubleshooting without replacing components. Clear status indication: toggle position and compatible auxiliary contacts allow quick identification of circuit condition for faster diagnostics. Key attributes Function: combined thermal and magnetic protection for overload and shortcircuit interruption, manual on/off operation, and reset capability. Compatibility: designed for use in standard electrical distribution systems and common panelboards; compatible with singlepole, doublepole, and multipole circuit configurations. Size and mounting: compact footprint with standard mounting options for DINrail or panel installation to suit residential, commercial, and light industrial panels. Materials: rigid thermoset housing with corrosionresistant copper alloy contacts and plated contact surfaces to maintain conductivity and resist arcing wear. Performance: consistent trip characteristics, stable thermal response across typical ambient conditions, and mechanical durability for frequent use. Practical applications Residential distribution panels: protect branch circuits for lighting and outlets, allow easy isolation for maintenance and upgrades. Commercial lighting and small power: provide reliable circuit protection in offices and retail spaces where compact breakers and clear circuit identification are needed. Motor and equipment protection in light industrial settings: interrupt motor stall and shortcircuit events and allow straightforward reset after fault clearance. Installation and maintenance notes Install in accordance with local electrical codes and standard wiring practices. Use appropriate conductor sizes and torque values at terminals. Compatible with common panel accessories such as busbar connections, auxiliary contacts, and shunt trip devices where additional remote control or signaling is required. Periodic inspection of terminal tightness and visual condition helps maintain reliable operation over the service life. Why choose this type of circuit breaker Provides essential circuit protection with predictable, repeatable performance across common electrical applications. Designed for straightforward installation, clear operation, and low maintenance to keep systems running and simplify servicing when faults occur.
