High-Power 3-Phase Control - Specifically engineered for heavy-duty US industrial equipment, this 3-phase switch safely handles power loads up to 30A at 208V–240VAC (Max rating 380VAC/3.7KW), providing reliable start/stop control for motors, pumps, and CNC machinery
Secure Self-Locking Design - Features a professional self-locking mechanism: pressing the "ON" button locks the circuit instantly in place, while the "OFF" button ensures an immediate, clean disconnect, guaranteeing precise and safe operation during high-frequency manual switching
Superior Silver Contacts - contacts that offer excellent electrical conductivity and heat resistance, significantly extending the lifespan of the motor starter switch even under rigorous industrial conditions
Durable Waterproof Plastic Case - Constructed with a high-impact, insulated plastic casing that is fully waterproof, dustproof, and oil-resistant, making it an ideal industrial control switch for harsh environments like machine shops and factory floors
Universal US Wiring Compatibility - Features a standard compact layout with 6 internal heavy-duty screw terminals; designed for versatile integration with both US standard 3-phase systems and single-phase 220V/240V power distribution panels

Product description

Baomain Industrial 3-Phase Self-Locking Push Button Switch – Reliable Control for Heavy-Duty Equipment The Baomain BMBSP-330 is a panel-mounted 3-phase (3P) push button switch for industrial/commercial applications, offering 30A/380V AC power control (3.7KW capacity). With a self-locking (maintained) mechanism, it keeps circuits securely ON/OFF until manually pressed, ensuring stable operation for motors, pumps, CNC machines, and heavy-duty machinery. This 30A 380V 3-phase AC switch enables precise power management for 3.7KW loads, ideal for manual switching in 3-phase systems like industrial control panels.

Key Features:

3-Pole (3P) Design: Safely controls 3-phase circuits up to 30A/380V AC (3.7KW).This switch can control three phases motor directly, no need to use magnetic switch or a contactor. It can also be wired as required for 2P control circuit applications.
Normally Open (NO) Contact: Default OFF position; press "ON" to lock the circuit.
High-Conductivity Contacts – Sensitive, low-resistance terminals ensure stable current transfer.
Screw-Terminal Wiring: Provides secure, vibration-proof connections for long-term reliability.
