DRMS Series Hybrid Motor Starters

The DRMS Series Hybrid Motor Starters are intelligent and convenient solutions for controlling 3-phase asynchronous motors. These compact devices can provide up to 6 functions in the same unit: Forward/Reverse, Soft Start/Soft Stop, Motor Overload Protection, and Mains Isolating Relay.

Motor overload detection is based on a thermal load curve. The relays are de-energized when an overload condition is present, ensuring a long service life.

Features:

• 3-phase motors reversing up to 4 kW
• 2-phase soft start/stop
• Up to 4 dials for setting of starting torque, deceleration torque, soft start/stop, and rated motor current
• 4 LEDs for status indication

The DRH Series is a family of compact DIN Rail Mount, IEC standard based Solid State Contactors with ratings up to 20 Amps per channel at 600 VAC. The DRH Series is ideal for heating applications up to 20A per phase, and can also be used to control (start/stop) 3-phase motors of up to 5HP at 480 VAC. It is an effective solution for replacement of electromechanical contactors in commercial and industrial applications that require frequent switching.

DRH Series contactors have an innovative design that increases the air flow thus improving the thermal performance and feature over-temperature protection to avoid overheating in case of a fan malfunction. They are available in 2 different versions with ratings up to 18 Amps (3 controlled legs) or up to 20 Amps (2 controlled legs).

Features:

• Built-in over-voltage protection
• Alarm output in case of over-temperature
• Enclosed heat sink, eliminating the need of providing earth connections
• AC or DC control
• Zero voltage and instantaneous turn-on output
• Multicolor LED with input status and alarm indication
• UL 100 kA Short Circuit Current Rating
• C-UL-US listed and CE compliant

Relays used for railway rolling stock are subject
to increasingly higher technical demands – such
as the need for wider operating ranges; higher
resistance to shock and vibration; operation over
a wider range of temperature and humidity; and
above all, the fire resistance properties of the
relay’s constituent parts.

Mechanical and Climate Characteristics

The resistance against random vibrations and shock of the relays and their sockets and accessories is in compliance with the prescription of EN 61373 standard for Category 1, Class B products.

Their resistance to temperature and humidity is in compliance with the prescription of EN 50155 standard, TX class (for relay and sockets) or T1 class (for timers and control relays).

Fire and Smoke Characteristics of the Materials

The relays and their sockets and accessories are manufactured using specific insulating materials, which satisfy the requirement R26 of fire protection prescribed by the standard EN 45545-2 +A1:2016 for product category EL10.

The requirement R26, for Hazardous levels HL1 to HL3, is the conformity to V0 class following vertical small flame test according to EN 60695-11-10.
