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.
