The SCHNEIDER ELECTRIC SQUARE D 36404 is an auxiliary switch designed for integration with Square D molded case circuit breakers. This component provides critical operational status feedback, mechanically linked to the main breaker's contact mechanism. It accurately reflects whether the associated circuit breaker is in the open or closed position, enabling enhanced system monitoring and control within industrial electrical distribution systems.

Technical details

• Series: Square D
• Functionality: Auxiliary switch for circuit breaker status indication (Open/Closed).
• Actuation: Mechanically linked to the main circuit breaker mechanism.
• Contact Type: Typically includes Form C (SPDT) contacts for signaling.
• Voltage Rating: Compatible with the voltage rating of the associated Square D circuit breaker; specific voltage rating for the auxiliary contacts themselves should be verified against the manufacturer's datasheet.
• Current Rating: Typically rated for low-voltage signaling circuits; specific current rating should be verified against the manufacturer's datasheet.
• Mounting: Designed for internal mounting within compatible Square D circuit breaker frames.
• Operating Temperature: Standard industrial operating temperature range; refer to manufacturer specifications for precise limits.

Applications & compatibility
