GN350ELZ Equivalent & Substitute Parts

Part Overview

The GN350ELZ is a solid-state relay (SSR) manufactured by Sensata-Crydom, configured as a 3PST-NO (3 Form A) module with 50A load current capacity. This DIN Rail mounted device operates with input voltage of 18–36VAC and supports load voltages from 48V to 600V with zero-cross AC output switching. The product is Active status and RoHS Compliant, designed for industrial control applications requiring reliable solid-state switching without mechanical contacts.

Substitute parts become necessary when DIN Rail mounting is not feasible, when different input voltage ranges are required, or when alternative packaging and termination configurations better suit specific installation environments.

Key Parameters

Substitute Part Grouping Explanation

The GN350ASZH qualifies as a functional substitute based on the following alignment of critical parameters:

• Circuit Configuration: Both devices are 3PST-NO (3 Form A) solid-state relays with identical switching topology
• Load Current: Both rated at 50A, supporting equivalent load capacity
• Output Type: Both provide AC switching with zero-cross functionality
• Termination Style: Both use screw terminals for field wiring
• Series Designation: Both belong to the GN3 series
• Compliance: Both are RoHS Compliant (GN350ASZH is ROHS3 Compliant)

The primary differences are mounting configuration (DIN Rail vs. Chassis/Panel Mount), input voltage range (18–36VAC vs. 24–255VAC/DC), and load voltage ceiling (600V vs. 510V). These differences define the substitution scope and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the GN350ELZ and GN350ASZH are Active products with current inventory availability and full RoHS compliance, meeting modern environmental and regulatory standards. The GN350ASZH carries ROHS3 Compliant status and includes REACH Unaffected designation, providing additional regulatory assurance for European applications.

Selection between these devices depends on installation constraints and electrical requirements:

• GN350ELZ is specified when DIN Rail mounting is required and input voltage remains within 18–36VAC with load voltages up to 600V
• GN350ASZH is applicable when chassis or panel mounting is preferred, when input voltage flexibility (24–255VAC/DC) is beneficial, and when load voltages do not exceed 510V

Both devices maintain identical 50A load current capacity, 3PST-NO switching topology, and zero-cross AC output characteristics, ensuring functional equivalence within their respective parameter boundaries.

Frequently Asked Questions (FAQ)

Q: Can GN350ASZH directly replace GN350ELZ in all applications?

A: Substitution is valid only when the application meets all of the following conditions: (1) mounting configuration can accommodate chassis or panel mount instead of DIN Rail, (2) input voltage supply is within 24–255VAC/DC range, and (3) maximum load voltage does not exceed 510V. If any condition is not met, substitution is not appropriate.

Q: What is the significance of the input voltage difference between these two models?

A: GN350ELZ accepts 18–36VAC input, while GN350ASZH accepts 24–255VAC/DC input. The GN350ASZH provides broader input voltage compatibility and accepts both AC and DC control signals. If your control circuit operates below 24VAC or above 255V, the GN350ELZ may be the only suitable option.

Q: Are there load voltage limitations when substituting?

A: Yes. GN350ELZ supports load voltages up to 600V, while GN350ASZH is rated to 510V maximum. Applications requiring load voltages above 510V must use GN350ELZ. Both devices support minimum load voltages of 48V and 24V respectively.

Q: Do both relays use the same termination method?

A: Yes. Both GN350ELZ and GN350ASZH use screw terminal connections, ensuring compatible field wiring practices. Termination compatibility does not restrict substitution; mounting type and electrical parameters are the determining factors.

Q: What is the difference between DIN Rail and Chassis/Panel Mount configurations?

A: DIN Rail mounting (GN350ELZ) uses standardized rail clips for installation on 35mm DIN rails, common in industrial control cabinets. Chassis/Panel Mount (GN350ASZH) requires direct fastening to an enclosure or panel surface. These are distinct mechanical interfaces and cannot be interchanged without physical modification.

Q: Are both products currently available?

A: Yes. Both GN350ELZ (835 Pcs) and GN350ASZH (985 Pcs) are listed as Active products with new original inventory in stock.
