Switchgear CPAL
Ваши преимущества
• Assured drainage reliability: Automatic duty rotation and instant switchover to the standby pump if a fault occurs keep critical infrastructure dry 24 / 7.
• Two intelligent operating modes: Choose Emergency Mode 1 (all pumps run until the sump reaches the minimum level) or Efficiency Mode 2 (pumps step in and out one-by-one as the level rises or falls) to match site priorities.
• Comprehensive motor protection: Dry-run cut-out, phase-failure relay, motor-protection breakers, and a dedicated moisture / temperature (PTC) relay for every submersible motor safeguard equipment and extend service life.
• Clear status at a glance: Individual run lamps, per-pump fault lamps, plus common SBM (run) and SSM (fault) relay contacts simplify diagnostics and remote monitoring.
• User-friendly control: Hand-0-Auto selector, external dry-contact start/stop terminals, and adjustable start/stop delays allow quick commissioning and manual override when needed.
• Flexible configuration: Controls up to four pumps with direct-on-line (DOL) or star–delta starters; system coding makes power, pump count, and starter type instantly recognisable.
• Rugged enclosure: Powder-coated steel cabinet with IP54 protection and built-in isolation transformer ensures safe operation in humid underground chambers.
Тип
Microprocessor-controlled CPA-L switchgear provides automatic or manual control of submersible pump stations arranged in 1 + 1, 2 + 1 or 3 + 1 duty/stand-by configurations (max. 4 pumps, up to 2.2 kW each in the standard model). Level floats feed the controller, which keeps one pump permanently on hot standby while the others share the workload. All power and control components including DOL or optional star–delta starters, isolation transformer and phase-failure relay are factory wired inside an IP54 wall-mount cabinet ready for quick connection to mains, floats and pumps.
