New to Magnet’s range of Schneider low voltage motor starting solutions, are the EasyPact TVS motor starters, designed for motor control and protection for simple applications.

The new E range, an extension of the current range, includes contactors, thermal overload relays, control relays and motor circuit breakers designed and precision-engineered to give OEMs and panel builders a motor starter solution that offers high-performance, safety of personnel and a competitive price.

“This range ensures compatibility and easy installation in new or existing motor control panels,” explains Brian Howarth, managing director, Magnet Group. “Direct mounting of the thermal overload underneath the contactor minimises cabling and installation time, also enhancing reliability of the system and saving panel space, which all contributes towards cost saving.

“An important feature of this system is that it has been designed for application optimisation, which means users are able to select only the components that are needed for each specific project. A clear reference system ensures easy product selection for every application, and because fewer components are required, design is simplified and stocking requirements are reduced.”

Features and benefits

The EasyPact TVS range encompasses nine sizes of contactors that cover a broad range of current ratings from 6-630 A. These are used in conjunction with thermal overload relays (0,1-630 A), industrial control relays with 4 NO/NC contacts, and a newly designed motor circuit breaker (0,1-32 A).

Utilisation categories are Class AC-1 for loads with power factor at least equal to 0,95 (resistive load, heating and distribution) and AC-3 for squirrel cage induction motors, with contactor breaking taking place when the motor is running.

Thermal overload relays protect AC circuits and motors against overloads, phase failures, long starting times and prolonged stalled rotor conditions. The thermal relay controls the current driven by the motor and if this current exceeds the setting, the auxiliary contacts will change state, causing the motor to stop.

Thermal-magnetic 3-pole protection motor circuit breakers are designed for connection by screw clamp terminals to ensure a secure, permanent and durable clamping, which is resistant to harsh environments, vibration and impact.

Magnetic elements for short circuit protection of the motor have a non-adjustable tripping threshold, which is equal to about 13 times the maximum setting current of thermal trips. Thermal elements for overload protection include automatic compensation for ambient temperature variations. For protection to personnel, all live parts are safeguarded against direct finger contact to IP20.

The EasyPact TVS range ensures coordination between protection and control components, which means there is a safe and fast restart after a short circuit. To ensure suitable protection of electrical components against fire, product damage or power loss, Magnet recommends installation of this system in a spacious CRN steel enclosure. Severe conditions including dust, humidity and high temperatures can expose personnel and equipment to serious risks.

The EasyPact TVS motor starter system, which is suitable for applications including HVAC, lighting in buildings, cooling or extraction fans, small pumps and mixer applications, manufacturing and conveyor belts, conforms to stringent international quality, safety and environmental specifications.
