LZ2H6X53BD

What type of device is this component?

It is a TeSys H reversing ultra-compact starter designed for direct-on-line control of three-phase motors. It combines forward and reverse motor control with adjustable thermal overload protection in a compact unit.

What control voltage does this starter require?

The starter uses a nominal 24 V DC control circuit. Its specified control voltage range is 19.2 to 30 V DC, with current consumption of no more than 40 mA at 24 V DC.

What is the thermal protection adjustment range?

The thermal protection can be adjusted from 1.5 to 9 A, allowing the setting to be matched to the rated current of the connected motor.

What motor power can this starter control?

The LZ2H6X53BD is rated for motors up to 3 kW at 400, 415, 440 or 500 V AC. It is also rated at 2.2 kW at 380 V AC and 1.5 kW at 220 or 230 V AC, subject to the stated operating conditions.

What is the rated operational current?

The rated operational current is 9 A at 500 V AC for AC-51 duty and 6.5 A at 500 V AC for AC-53A duty. When units are mounted side by side, the respective ratings are reduced to 7 A and 5 A.

Does this starter provide reversing motor control?

Yes. It is a three-pole reversing starter designed to control both forward and reverse rotation of a compatible three-phase motor.

Which overload trip class does the starter use?

It uses thermal overload Class 10A in accordance with IEC 60947-4-2.

How is the component mounted?

The unit clips onto a DIN rail. Its slim 22.5 mm width makes it suitable for control panels where installation space is limited.

What type of terminals are fitted?

The starter uses spring-clamp terminals. They accept rigid conductors from 0.2 to 2.5 mm², flexible conductors from 0.2 to 2.5 mm² without cable ends, and flexible conductors from 0.25 to 2.5 mm² with cable ends.

Does the unit include a fault-signalling contact?

Yes. It includes one changeover auxiliary contact for fault signalling, enabling its status to be incorporated into a control or indication circuit.

What reset methods are provided?

The starter provides manual, automatic and electrical reset options, allowing the reset method to be selected according to the machine control arrangement.

What are the dimensions and weight?

The unit measures approximately 22.5 mm wide, 99 mm high and 114.5 mm deep. Its stated product weight is 212 g.

What operating temperatures are permitted?

It can operate from -25 to 30 °C without derating. Operation from above 30 to 70 °C is permitted with derating, while the specified storage range is -40 to 80 °C.

What ingress protection rating does it have?

The starter has an IP20 rating. It is therefore intended for installation inside a suitable electrical enclosure rather than direct exposure to moisture or contaminants.

What is the maximum operating rate?

The specified maximum rate is 120 cycles per minute for AC-51 duty at 50% on-time and 6 cycles per minute for AC-53A duty at 50% on-time.

Which electrical standards and certifications apply?

The component is specified as conforming to IEC 60947-4-2 and UL 60947-4-1, with CE and cULus certifications.

What are the insulation and impulse voltage ratings?

The rated insulation voltage is 500 V AC at 50/60 Hz, and the rated impulse withstand voltage is 6 kV.

What applications commonly use this starter?

Typical applications include compact motor-control panels for conveyors, pumps, fans, mixers and other machinery requiring direct-on-line starting with forward and reverse operation.
