Bender GmbH rcm465y-13 Residual Current Monitor

The Bender RCM465Y-13 Residual Current Monitor is a single‑channel, AC‑sensitive device that continuously monitors residual currents with an integrated measuring‑current transformer (Ø26 mm) and signals when the threshold of 30–300 mA is exceeded, with an adjustable response delay of 0–1 s. Configured for Type A operation, it runs over 40–400 Hz and presents a 220 Ω load for sensing; the unit displays status with Power On and Alarm LEDs, and features an internal TEST button for quick verification. It uses screw terminals for connection to 24–12 AWG conductors, and is housed in the X465 polycarbonate enclosure, mounting on a DIN rail (IEC 60715) or via two M4 screws, with IP30/IP20 protection and UL94V‑0 flammability. The RCM465Y‑13 variant is powered from AC 90–132 V (other supply voltages available on request); standard RCM465Y variants use 230 V. It complies with IEC 62020 and weighs ≤ 190 g. Ordering information: RCM465Y‑13 (Art. No. B 9401 2033). This residual current monitor provides early warning of leakage currents in electrical installations, signaling alarms before thresholds are reached and helping maintain safety in systems with earthed power networks.
