Thermal Magnetic Circuit Breaker 100A 1P DC Battery Protection Switch with Dual Protection and Fast Response

ThermalMagnetic Circuit Breaker, Size 1P1P, Marked 100a Description This singlepole thermalmagnetic circuit breaker combines thermal overload protection and magnetic shortcircuit protection in a compact 1P package. The device is marked 100a, indicating a 100 A rating for use where a singlepole, current protective device is required. Key benefits Dual protection: Thermal element limits damage from sustained overloads while the magnetic element trips on fast shortcircuit faults, protecting wiring and equipment. Clear specification: Singlepole 1P size simplifies selection for branch circuits where one conductor needs protection. Marked 100a for straightforward identification of the 100 A rating. Space efficient: Compact form factor fits into standard distribution modules and small control panels, conserving panel space. Reliable operation: Designed for repeatable tripping and reset performance to minimize downtime and support routine maintenance. Important attributes Function: Thermalmagnetic trip mechanism for combined overload and shortcircuit protection. Size and compatibility: 1P1P singlepole configuration suitable for singlephase branch circuits and control circuits. Rating: Marked 100a corresponding to a 100 ampere nominal rating. Construction: Rugged, serviceready design intended for panel mounting and regular use. Performance: Fast magnetic response for short circuits and timedelayed thermal response for overload conditions, allowing selective protection of downstream devices. Typical applications Protection of lighting and general power branch circuits in commercial or industrial distribution panels. Motor control circuits where singlepole protection is required for control supplies or auxiliary circuits. Small machinery and equipment control panels that need compact, current singlepole protective devices. Installation and maintenance notes Install in accordance with applicable wiring practices and ensure the device is used on circuits matching the marked 100a rating. Periodic inspection and testing are recommended to confirm correct operation and to reset or devices that have tripped or reached end of service life. This thermalmagnetic circuit breaker provides combined overload and shortcircuit protection in a compact singlepole 1P package marked 100a for straightforward selection and consistent panel integration.
