This model is identical to the 414 except that a meter-relay replaces the panel meter. An adjustable contact pointer is built into the meter-relay, When the indicating pointer rises to the value set with the adjustable contact, the contacts lock and actuate an internal relay. The relay's SPDT 5-ampere contacts are brought out through an AN connector at the back of the chassis. A manual reset button is supplied on the front panel. Reset connections are also brought out through the AN connector for rem&e resetting of the locked-up meter-relay.
