Protection Relays

Voltage Monitoring Relays

350 SERIES

3-phase voltage/phase monitor

Description

The 350 Series is a heavy-duty voltage monitor. This product

should be used when high current relays or dual contacts are

required, or 480V controls are used. Since the 350 Series uses

heavy-duty relays, it comes in fixed voltage range models rather

than a dual auto-ranging version like the Model 250.

The 350200 has a 15A general purpose contact. The 350400

provides a SPDT (Form C) relay rated to switch up to 600V,

allowing the use of 480V controls, eliminating the need for a

control power transformer to step the voltage down to

120-240V. Several DPDT (two Form C contacts) relay models

are also available.

The 350 microcontroller-based family of products are low cost

yet highly advanced solutions to heavy-duty problems. The 350

includes advanced single LED diagnostics. Five different light

patterns distinguish faults and normal operating conditions.

Other options such as high voltage trip and adjustable restart

delay are available.

on some models

BENEFITS

Constantly monitors 3 phase voltage to protect

against harmful line conditions, even before the

motor is started

Provides diagnostics which can be used for

troubleshooting and to determine relay status

Allows staggered start up of multiple motors, after

a fault, to prevent a low voltage condition

Eliminates the need for a control transformer to step

voltage down to 120 - 240V for a control circuit
