Description
3-PHASE VOLT MON/ 38
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 480 V 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 15 A general purpose contact. The 350400
provides a SPDT (Form C) relay rated to switch up to 600 V,
allowing the use of 480 V controls, eliminating the need for a
control power transformer to step the voltage down to
120–240 V. 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.
Features & Benefits
FEATURES BENEFITS
Proprietary
microcontroller
based circuitry
Constantly monitors 3 phase voltage to protect
against harmful line conditions, even before the
motor is started
Advanced LED indication Provides diagnostics which can be used for
troubleshooting and to determine relay status
Adjustable restart delay
(-2 models) settings Allows staggered start up of multiple motors, after
a fault, to prevent a low voltage condition
600 V rated relay
contacts available
on some models
Eliminates the need for a control transformer to step
voltage down to 120–240 V for a control circui
