The NewElec LA electronic motor protection relay provides superior thermal overload (50) and phase unbalance and single protection in applications that would traditionally have used thermal bi-metal relays. The LA Relay can also be fitted below a VSD drive.
Features include overload, underload, earth leakage, unbalance (single phase), over and under voltage, phase rotation and 3 independent PTC thermal censors.
Thermal (50) overload protection with full thermal memory and a fixed Class15 (cold), Class 5 (hot) This microprocessor based electronic motor protection relay, designed to IEC 60255-8, provides overload protection for cyclic or sustained loads, as well as providing unbalanced current and single phasing protection.

The LA relay has been packaged with integral three phase current transformer module block with 22mm primary apertures facilitates 'straight through' conductor routing from the main contactor to the electric motor in the range of 1 to 250 Amps. Powered for terminal block selectable 110/220 vac control supply with potential free n/o and n/c output contact rated 220 vac 5 amp
