Schneider Electric (Telemecanique) LD4LC30H5 with LB1‑LC03M17 Self Protected Motor Controller

The LD4LC30H5 with LB1‑LC03M17 is a Schneider Electric (Telemecanique) Integral 32 motor starter assembly.

• LD4LC30H5 is a 32A, 600V AC non‑reversing motor starter/contactor module.
• LB1‑LC03M17 is a thermal‑magnetic protection module (overload relay) rated for 10–16A, designed to mount directly on the LD4LC30H5 to provide overload and short‑circuit protection.

Together, they form a self‑protected combination motor controller suitable for 3‑phase motors in industrial applications.
