Schneider Electric 8736-SB0-4 Contactor

Schneider Electric's Square D 8736-SB0-4 is a NEMA-size 0, three-pole reversing motor starter (contactor) designed for forward/reverse control of 3‑phase motors. It uses a 120 V AC control coil and is built as an open-type unit with no auxiliary contacts. The contactor is rated for up to 18 A and up to 5 HP at 575 VAC, making it suitable for compact motor-starting applications at higher line voltages. It carries a 5 kA short-circuit rating (SSCR) and employs melting alloy overload protection. Maximum voltage rating is 600 VAC, enabling use with common industrial power supplies, and the 8736-SB0-4 family is specified as a reversing Type S starter with 3 poles and no line or load-side interlocks beyond basic contact protection.
