WELL-GUARD® Pump Panels

Full Voltage Type, Type NS, SS, XS

Class 8940 / Refer to Catalog 8940CT9701

Motor Logic SSOLR are designed to protect 50/60 hertz three-phase AC motors from overload, phase unbalance and phase loss conditions. Open Delta systems or grounded B-phase systems are difficult to balance and could cause the Motor Logic SSOLR to trip. For applications of this nature, it is recommended that bi-metallic overload relays (Form B12) be used.

Class 8940 Type NS, SS, and XS panels in NEMA 3R enclosures are specifically designed for pumping applications. Extra space is provided for field installation of auxiliary equipment.

●	Type S Contactor provided as standard

●	Approved for submersible pump applications

●	Class 10 Motor Logic® SSOLR through 200 hp–480 V, 100 hp–240 V, Type SS only

●	All prices include a START push button and a HAND-OFF-AUTO selector switch

●	Adjustable trip current

●	Phase failure sensitive through 200 hp–480 V, 100 hp–240 V, Type SS only

●	Ambient temperature compensated overload

●	All devices are UL Listed, and marked “SUITABLE ONLY FOR USE AS SERVICE EQUIPMENT”

a	To substitute an IEC ambient compensated bimetallic overload relay (up to size 5) for the MOTOR LOGIC SSOLR, request Form B12 and state motor hp (no charge). This applies to the above (SSx) devices only.

b	See page 16-87 for coil voltage codes and pricing.

c	Fuse clips are sized for use with dual-element time-delay fuses.

d	Voltage code not required for 240 V or 480 V common control with 8940SS controllers.

e	Circuit breaker disconnect supplied. (See page 7-31 for circuit breaker adjusment range.)

f	See page 7-31 for circuit breaker adjustment range.
