Ex9IRZ32-32 BO 4R EU

The Ex9IRZ32 is a manually operated DC Rotary Switch Disconnector designed for isolating and switching photovoltaic circuits. It is suitable for applications up to 1200 V DC and rated currents up to 32 A. The device can disconnect 1 to 2 MPPT lines simultaneously and is ideal for infrequent switching operations such as maintenance or system upgrades in solar installations. Complies with EN IEC 60947-3 and conforms to utilization categories DC-PV1 and DC-PV2, ensuring reliable operation under demanding PV conditions including bidirectional current flow and high overcurrents in parallel-connected strings. It features silver-plated contacts for reliable conductivity, arc suppression time below 3 ms, and degree of protection IP66. The Ex9IRZ32 is available in DIN-rail mounted and enclosed (IP66) box versions, with 4-pole configuration and optional locking in the OFF position. Connection options include a standard 4-pole version without designation, and variants with clearly defined input/output directions: 4T – top input and output, 4B – bottom input and output, 4S – top input and bottom output
