WAGO 787-3664 elektroninen johdonsuojakatkaisija 4-kanava 24 V DC

The WAGO 787-3664 is a 4-channel electronic circuit breaker designed for 24 V DC applications. It provides selective overcurrent protection for each output channel, with adjustable current limits from 0.5 A to 6 A per channel and a total output current of up to 24 A. This device is ideal for protecting control circuits, sensors, actuators, and other DC loads in industrial automation and building infrastructure.

Advantages

• Selective protection: Each channel trips independently, minimizing downtime.
• Adjustable current per channel: Flexible configuration for different loads.
• Remote reset and manual reset: Convenient operation and integration.
• Push-in CAGE CLAMP® connection: Fast, tool-free wiring.
• Compact DIN-rail mount: Saves space in control cabinets.
