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 indicator light.
• Mains connection 3~, 230 V with optional switching plug.
• Pump housing in bronze 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 integrated tripping.
• Fault acknowledgement.
• Dual pump management (two single pumps installed in parallel) Main/standby operation (automatic fault-actuated switchover/time-sensitive pump alteration)
