The SMM5-630L is a high-performance Molded Case Circuit Breaker (MCCB) with integrated leakage protection, developed by Zhejiang Shanmeng Electric Co., Ltd. Designed for low-voltage power grids (AC 50/60Hz), it operates at a rated voltage of AC 400V and supports rated currents of 400A/630A, making it suitable for both household and industrial power distribution systems. This breaker provides comprehensive protection against overload, short-circuit, and ground fault currents, ensuring the safety of electrical equipment and personnel. It fully complies with international standards IEC 60947-2 and national standard GB/T 14048.2, guaranteeing reliable performance in diverse operating environments.
Equipped with a high-sensitivity leakage detection module, the SMM5-630L instantly identifies abnormal residual currents (25-1000mA) and automatically trips within 0.01-2 seconds, effectively preventing electric shocks and fire hazards caused by insulation damage.
With a limit short-circuit breaking capacity (Icu) of 65kA, the breaker quickly cuts off fault currents during short-circuit events, minimizing damage to wires and equipment. Its advanced arc-extinguishing system ensures fast arc quenching, reducing energy loss and extending service life.
Optimized for harsh conditions, the SMM5-630L works stably at ambient temperatures ranging from -5℃ to 40℃ (with a 24-hour average not exceeding 35℃). Its rated reference temperature of 40℃ ensures consistent protection performance even in high-temperature industrial settings.
The modular structure allows easy expansion with accessories like auxiliary contacts, alarm contacts, and undervoltage releases, adapting to customized protection needs. Its compact size (e.g., 140×43.5×184.8mm for 400A variant) saves cabinet space, simplifying installation in tight layouts.
A clear-positioned operating handle enables quick identification of "ON/OFF" status. Built-in indicators for overload, pre-alarm, and leakage faults help maintenance personnel diagnose issues efficiently.
Our engineers provide personalized selection guidance, analyzing load characteristics to recommend optimal SMM5-630L configurations.
Adequate inventory ensures 3-7 day delivery for standard models, reducing project downtime.
We offer free installation tutorials, online fault troubleshooting, and a 12-month warranty. Replacement parts are supplied within 48 hours for urgent needs.
Tailor-made accessories (e.g., electric operating mechanisms) are available to match specific automation system requirements.
Yes, it supports both vertical and horizontal installation, flexible for different cabinet designs.
It adjusts between 25mA and 1000mA, suitable for protecting household appliances and industrial motors.
Yes, compliance with IEC 60947-2 ensures it meets EU safety requirements for export projects.
Yes, its overload long-delay inverse-time characteristic matches motor startup currents, making it ideal for infrequent motor starting.
