1-6 General Information MN894
Configurations
Control Only: Soft start control, without motor overload protection or branch circuit
protection circuit breaker or fusible disconnect switch. Suitable for installation with a
series contactor or as a retrofit for an existing motor starter.
Non-combination Starter: Soft start control with motor overload protection, less branch
circuit protection circuit breaker or fusible disconnect switch. Installation with existing
branch circuit protection would use this configuration.
Combination Starter: Soft start control with motor overload protection and branch circuit
protection and branch circuit protection circuit breaker or fusible disconnect switch. Only
push buttons are required to complete the system. New installations with no existing
control equipment would use this configuration.
Bypass System, Control Only: Soft start control without overload protection and branch
protection. Includes a bypass contactor to shunt the power cells after the control is in the
full run mode to eliminate heat generation across the power cells. Allows installation in a
NEMA 4 or NEMA 12 enclosure.
Bypass System, Non-combination: Soft start control noncombination system with
motor overload protection, less branch circuit protection. Includes a bypass contactor to
shunt the power cells after the starter is in the full run mode to eliminate heat generation
across the power cells. Allows installation in a NEMA 4 or NEMA 12 enclosure.
Bypass System, Combination: Soft start control combination system with motor
overload protection and branch circuit protection circuit breaker or fusible disconnect
switch. Includes a bypass contactor to shunt the power cells after the starter is in the full
run mode to eliminate heat generation across the power cells. Allows installation in a
NEMA 4 or NEMA 12 enclosure.
Enclosures and Ventilation: Soft start controls are available in panel mount or in NEMA
type 1, 12, 3R enclosures. The control will generate approximately 3.3 watts of heat per
running ampere during operation. All factory supplied enclosures are designed to
dissipate this heat under maximum specified operating conditions. If the multipurpose
control is mounted in an enclosure not supplied by the factory, this heat dissipation must
be considered. Adequate ventilation or convection cooling should be provided unless a
bypass contactor is used.
Panel Mount: Soft start control mounted on a panel with provisions for wall or enclosure
installation.
NEMA Type 1 (IP23): Soft start control mounted in a ventilated NEMA type 1 panel
enclosure. Intended for indoor use primarily to provide a degree of protection against
contact with enclosed electrical components. Available for all sizes and configurations.
NEMA 12/3R (IP65/IP32): NEMA 12 enclosure provides protection from dust, dirt, oil
and water. NEMA 3R outdoor installation protects from rain, sleet and snow. A NEMA
12/3R is shipped as a NEMA 12 and to convert to NEMA 3R, remove the drain screw at
the bottom of the enclosure.
