Range of electrical control solutions

24 November 2021 Power Electronics / Power Management

A range of Hartland Controls’ motor run capacitors, definite purpose contactors, transformers and other electrical control solutions is now available from Mouser and, by extension, from local distributor TRX Electronics.

The Hartland Controls (a Littelfuse company) HCK motor run capacitors boost the current or reduce the power factor to an electrical motor, delivering reliable power supply for a range of applications, including HVAC, food and beverage, electronics, and pools and spas. The start capacitors offer 370 V a.c. and 440 V a.c. rated voltage as standard, with 0,1% maximum dissipation factor and 30 µA maximum leakage current.

HCT 40 VA, 50 VA and 75 VA transformers efficiently change one AC voltage to another by magnetic induction. The 40 VA and 50 VA transformers are inherently limited, requiring no secondary fusing, while the 75 VA transformers are not inherently limited and do require secondary fusing. The transformers are ideal for applications such as food service, water pumps and HVAC.

The HCD series three-pole definite-purpose contactors use three wires to control electrical current direction and are typically used in commercial applications. The contactors are rated for 50 FLA to 120 FLA and feature a +130°C Class B insulation system.

HCC series devices are also three-pole definite-purpose contactors, rated for 50 FLA to 60 FLA. The contactors feature a double-E magnet assembly for optimal performance with reduced power use, in addition to an actuator moulded from high arc-resistant polyester. The contactors offer reliable performance for commercial and residential HVAC, water and wastewater, and electric vehicle (EV) charging.
