Melting Alloy Overload Relay Jumper Strap Kits
Jumper strap kits are used only on three-phase magnetic starters with
melting alloy overload relays, where a three-phase starter is used to
control a single-phase motor. These kits include two jumper straps, a
wiring diagram showing how to wire a three-phase starter to control a
single-phase motor, and thermal unit selection tables for single-phase
operation.
