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).
