Phoenix Contact ELR H5-IES-SC-24DC/500AC-2 Hybrid Motor Starter 2.4A 24V DC

The Phoenix Contact ELR H5-IES-SC-24DC/500AC-2 is a high-performance hybrid motor starter engineered for the reliable switching and protection of three-phase AC motors. This compact device combines semiconductor technology with robust relay mechanics to ensure long service life and efficient operation. It is specifically designed for reversing applications, providing seamless control for motors with an output current of up to 2.4 A and a voltage range of up to 500 V AC. With an integrated emergency stop function and safety certification, it meets stringent industrial requirements for operational safety.

Advantages

The hybrid technology utilized in this motor starter significantly reduces wear on mechanical contacts, leading to a longer operational lifespan compared to traditional contactors. Its compact design saves valuable space in control cabinets, while the integrated safety features, including SIL 3 and PL e compliance, simplify the implementation of safety-critical systems. The device also offers adjustable overload shutdown, allowing for precise protection tailored to the specific motor being controlled, which helps prevent damage and reduces downtime in industrial processes.

Suitable for

• Reversing three-phase AC motors in industrial automation
• Safety-critical applications requiring emergency stop functionality
• Systems where space-saving and long-lasting switching components are essential
• Motor control circuits operating at 24V DC control voltage

This motor starter may not be suitable for applications requiring current ratings exceeding 2.4 A or for environments where the ambient conditions exceed the IP20 protection rating without additional enclosure protection. It is also not intended for use in non-industrial settings or with motor types that are incompatible with standard AC induction motor control parameters.

Key specifications

• Output current: up to 2.4 A
• Control voltage: 24 V DC
• Operating voltage: up to 500 V AC
• Safety ratings: SIL 3 / PL e
• Connection type: Screw connection
• Protection rating: IP20

Installation should be performed by qualified personnel in accordance with local electrical regulations. The device is mounted on a standard DIN rail within a control cabinet. Ensure that the control voltage is correctly wired to the input terminals and that the motor leads are securely fastened to the output terminals using the provided screw connections. Configure the overload shutdown settings according to the nominal current of the connected motor to ensure proper protection.

What to consider before purchase

• Verify that the motor's nominal current does not exceed 2.4 A
• Ensure the control system provides a stable 24V DC supply
• Check that the installation environment meets the IP20 protection requirements
• Confirm that the safety requirements align with SIL 3 / PL e standards

Regularly inspect the screw connections for tightness and verify that the overload settings remain appropriate for the motor load to maintain optimal safety and performance.
