The TOV relays are over or undervoltage relays, single phase or three phase,
instantaneous or fixed time adjustable from 0.1 to 25.5 s.
The settings are adjusted using the switches located on the front side of the relay.
The single phase type relays include a filter for the third harmonic. The three phase
models do not include that filter.
The TOV relays are modular solid state relays and are supplied to the customer in a
1/8 rack case, allowing it to be a part of a distribution system.
