Type of pressure relief Single-row arrangement (plan view) 1) For panel replacement, wall-standing > 2750 mm For panel replacement, free-standing > 3000 mm 2) If smaller distances are required, please consult PLM 3) For wall-standing panels, both ends must be closed due to backward pressure relief from connection compartment in the event of internal arc fault. To prevent rear access to switchgear, the factory provides rear cover plates (standard: 200 mm depth) to close both ends. 4) For free-standing application only Circuit-Breaker Switchgear Type 8BT2 ■ Siemens HA 26.41 ■ 2019
