NewElec’s 100 M series relays meet the very specific protection requirements of coal cutting machinery, underground motors and transformers and their related supply cables. Affordable and user friendly, the relays are designed for installation inside relatively confined spaces, flameproof enclosures and gate end boxes.
The relays cater for start acceleration times of 2 to 10 s with overload protection provided for cyclic and sustained overloading conditions. They have a non-volatile thermal memory calibrated in 6, 12, 18, or 120 stops/starts per hour and a thermal memory decay that is ideal for running and standstill conditions.
Motors and machinery are provided with protection against phase unbalance and loss, even on lightly loaded motors. The relays provide thermal protection for motor and supply cables as well as overall short circuit protection. During operation the relays ensure that the main contactor is not used to clear potentially damaging high energy faults, and user friendly labelled dials indicate motor load, start time and short circuit levels. Any fault condition is identified by panel mounted latched fault diagnostic LEDs.
With a small 52x113 mm footprint, the relays plug into a chassis-mounted 11-pin base for ease of maintenance. The 100 M Series is available from 5 to 360 A and also in percentage calibration. The series is ideal for general purpose use with underground motors having safe hot stall times of up to 10 s, as well as being suitable for use on motors connected to high inertia loads.
