| Datasheet | Download Datasheet |
The ATC Diversified CMB-24-AFA-1 is an AC go/no-go current monitor. The monitored conductor passes through its built-in current transformer, so it detects whether current is flowing without any connection to the line.
Sensing: built-in current transformer (through-hole, no connection to the line). Current: up to 50 A. Control supply: 24 V AC. Trip point: fixed at 1 A. Trip delay: 30 ms. Reset delay: 0.5 s. Reset: automatic.
Output: SPDT, 10 A resistive at 240 V AC; 211 VA inductive at 120 V AC; 1/6 HP at 120 V AC, 1/3 HP at 240 V AC. Mounting: plug-in. Approvals: cULus Listed (E55826). It operates from 0 to +55 °C and stores from -45 to +85 °C.
