Phoenix Contact 2297303 Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2297303 is a 3-phase reversing contactor from the ELR W3 series, designed for AC load switching with zero-cross capability. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for system maintenance and component replacement in industrial control applications.

The 2297303 operates as a 3PST-NO (3 Form A) relay with a 2 A load current rating, 230VAC input voltage, and load voltage range of 48–575V. Its DIN rail mounting and screw terminal configuration support standard industrial panel integration.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 2297303 is determined by the following critical parameters:

• Circuit Configuration: Must maintain 3PST-NO (3 Form A) topology for equivalent switching functionality
• Output Type: AC operation with zero-cross capability required for load protection and EMI reduction
• Input Voltage: 230VAC nominal input specification
• Load Current Rating: Minimum 2 A capacity; higher ratings provide operational margin
• Load Voltage Range: Must encompass or exceed the 48–575V specification
• Mounting and Termination: DIN rail compatibility with screw terminal interface for direct panel integration
• RoHS Compliance: Environmental and regulatory alignment with original specification

The Sensata-Crydom DRC3P48A400 satisfies these substitution criteria through matching circuit topology, output characteristics, input voltage range, and mounting configuration.

Parameter Comparison

Engineering Selection Recommendations

The Sensata-Crydom DRC3P48A400 is an active-status equivalent for the obsolete Phoenix Contact 2297303. Both components share identical circuit topology (3PST-NO), output characteristics (AC, zero-cross), termination method (screw terminal), and DIN rail mounting capability. Both maintain RoHS compliance.

The DRC3P48A400 provides a 5 A load current rating compared to the 2 A specification of the 2297303, offering increased operational margin within the same circuit class. Input voltage range (208–265VAC) encompasses the 230VAC requirement. Load voltage range (48–530V) covers the primary operating band of the original specification, with the upper limit 45V below the original 575V maximum.

Active product status of the DRC3P48A400 ensures ongoing availability and supply chain continuity for replacement and new installations.

Frequently Asked Questions (FAQ)

Q: Can the DRC3P48A400 directly replace the Phoenix Contact 2297303?

A: Yes. Both components share 3PST-NO circuit configuration, AC zero-cross output type, 230VAC input voltage compatibility, screw terminal termination, and DIN rail mounting. The higher 5 A load current rating of the DRC3P48A400 provides operational margin for 2 A applications.

Q: What is the significance of the load voltage difference (575V vs. 530V)?

A: The DRC3P48A400 supports load voltages up to 530V, which covers standard industrial AC supply levels (48V, 120V, 208V, 240V, 277V, 380V, 415V, 480V). Applications requiring operation above 530V require evaluation against specific load requirements.

Q: Does the DRC3P48A400 support both chassis mount and DIN rail mounting?

A: Yes. The DRC3P48A400 is specified for both chassis mount and DIN rail mounting configurations, providing installation flexibility beyond the DIN rail-only specification of the 2297303.

Q: Are both components RoHS compliant?

A: Yes. Both the Phoenix Contact 2297303 and Sensata-Crydom DRC3P48A400 are RoHS compliant, meeting environmental and regulatory requirements for industrial applications.

Q: Why is the Phoenix Contact 2297303 classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by Phoenix Contact. The DRC3P48A400, with active product status, ensures continued availability and supply chain support for replacement applications.
