Delay from Phase loss (tr): 150mS (worst case = tr x 2) BEFORE INSTALLATION, ISOLATE THE SUPPLY. Power on delay (Td): 1 sec. (worst case = Td x 2) Connect the unit as required. The Connection Diagram below shows a typical installation, Power on indication: Green LED whereby the supply to a load is being monitored by the Phase monitoring relay. If a fault should Relay status indication: Red LED occur (i.e. fuse blowing), the relay will de-energise and assuming control of the external Ambient temp: -20 to +60C Contactor, de-energise the Contactor as well.

Weight: 75g Mounting option: On to 35mm symmetric DIN rail to BS EN 60715 This device is not suitable for applications where there could be a percentage of re-generative voltage or direct surface mounting via 2 x M3.5 or 4BA screws present during a fault condition, i.e. fuse failure. During these conditions a monitor that includes an using the black clips provided on the rear of the unit. adjustable under voltage trip level is necessary which allows this type of fault to be detected. It is 2 Terminal conductor size 2 x 2.5mm solid or stranded therefore recommended that the LXPRT or LXPRT-4W phase monitors be considered. Approvals: Conforms to IEC. CE, and RoHS Compliant.
