Relays - 1500 Induction Style Relay|
Substitute for Warrick Series 1 Relay Induction Style Relay - The Series 1500 induction style relay with field
convertible contacts provides a versatile and reliable liquid level control. The design also makes the 1500 one of the most durable relays
available Applications such as pump-control, level alarms and long distance applications can be easily performed with this device. Available
with 1,2 or 3 isolated double break contacts, all rated at 25 amp @ 120V or 240 VAC. This device is UL & CSA recognized.
The B/W 1500 induction relay utilizes the liquid as an electrical conductor to complete the secondary circuit between the upper and lower
electrodes. Thus, when the liquid contacts the upper electrode, the resulting flow of current in this circuit sets up a bucking action in the
lower bar of the core. This action tends to divert lines of magnetic force to the core legs and sets up an attraction that pulls the armature
in to contact with the legs. This armature movement closes the electrode and load contacts.
