including 320721-768

Use a DC microammeter connected to the FC+ and FC- terminals

The hermetically sealed sensor and tamper-proof construction ensure consistent performance in demanding environments

Durable Construction: High-grade housing and 1/4" barb fittings resist cracking and vibration-induced failure

which breaks both power lines to the load for increased safety and complete circuit isolation during the "off" cycle
