ABB DC Load-Break Switch for 2 MPPTs

ABB DC Load-Break Switch OTDCP32SA22MD, 4-Pole, 32 A, for 2 MPPTs

The ABB OTDCP32SA22MD is a 4-pole DC isolator for the simultaneous disconnection of two independent PV strings – ideal for inverters with two MPPT inputs. It is suitable for DC voltages up to 1000 V DC at a rated current of 32 A. Each of the two circuits is switched separately via two poles each, ensuring safe and standards-compliant isolation of the PV strings. The compact, UV-resistant plastic housing with IP65 protection rating allows use indoors and outdoors – even under harsh conditions.
