Equipment and function

• Manual power adjustment with 3 speed stages.
• Pumps with 1~ motor: P2 up to 90 W: internal protection against unacceptably high winding temperatures; P2 = 180 W: Full motor protection with thermal winding contacts in conjunction with tripping unit.
• Pumps with 3~ motor: P2 up to 90 W: internal protection against unacceptably high winding temperatures; P2 ≥ 180 W: Full motor protection with integrated trip electronics.
• Fault signal light.
• Contact for collective fault signal.
• Direction of rotation signal lamp.
• Mains connection 3~, 230 V with optional switching plug.
• Pump housing in red brass or grey cast iron (stainless steel depending on type).
• PN 6/PN 10 combination flange (for DN 40 to DN 65).
• Thermal insulation shells.
• Additional functions by retrofittable Protect Module C: SSM fault signal as potential-free NC contact, SBM run signal as potential-free NO contact
• "Overriding Off" control input via external potential-free contact (NC contact).
• Blocking detection.
• Full motor protection with tripping unit.
• Fault acknowledgement.
• Dual pump management (two single pumps installed in parallel) Main/standby operation (automatic fault-actuated switchover/time-sensitive pump alteration).
