Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 2910375 is determined by the following critical parameters:

Primary Substitution Criteria:

• Category: Transient Voltage Suppressors (TVS) / Circuit Protection
• Mounting Type: DIN Rail
• Operating Temperature Range: -40°C ~ 80°C minimum
• RoHS Compliance: ROHS3 Compliant
• Regulatory Approvals: UL certification required

Electrical Compatibility Considerations:

• Voltage - Continuous Operating (Max) (MCOV): Must support minimum 385VAC
• Current - Discharge (Max) (8/20µS): Must support minimum 40 kA
• Voltage - Protection Level (VP) (2416): Must support minimum 4 kV

The substitute part SPD2-300-4P0-R is identified based on shared category classification, DIN rail mounting, compatible operating temperature range, ROHS3 compliance, and UL certification. However, electrical parameter differences exist and must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 2910375 and Littelfuse SPD2-300-4P0-R maintain active product status and ROHS3 compliance. Both devices are UL-certified and support the required -40°C to 80°C operating temperature range with DIN rail mounting.

The Phoenix Contact 2910375 is specified for 277/480V systems with higher continuous operating voltage (385VAC MCOV) and higher protection voltage ratings (2.5 kV VPR, 4 kV VP). The Littelfuse SPD2-300-4P0-R operates at 300VAC MCOV with lower protection voltage ratings (900 V VPR, 1.5 kV VP) but provides higher short-circuit current rating (150 kA SCCR) and includes thermally protected and remote signaling contact features.

Selection between these devices depends on system voltage requirements and surge protection specifications. The Phoenix Contact device is appropriate for higher-voltage applications, while the Littelfuse device is suitable for lower-voltage systems requiring enhanced short-circuit protection and signaling capabilities.

Frequently Asked Questions (FAQ)

Q: Can the Littelfuse SPD2-300-4P0-R directly replace the Phoenix Contact 2910375?

A: Direct replacement is not recommended. The Littelfuse device operates at 300VAC MCOV compared to the Phoenix Contact's 385VAC MCOV. The protection voltage ratings differ significantly (1.5 kV VP versus 4 kV VP). Application voltage requirements must be evaluated before substitution.

Q: What are the key electrical differences between these devices?

A: The Phoenix Contact 2910375 provides higher continuous operating voltage (385VAC) and higher protection voltage levels (2.5 kV VPR, 4 kV VP). The Littelfuse SPD2-300-4P0-R operates at lower voltage (300VAC MCOV) but offers higher short-circuit current rating (150 kA SCCR versus 25 kA SCRR) and includes thermally protected and remote signaling contact features.

Q: Are both devices DIN rail mountable?

A: Yes, both devices are DIN rail-mounted and support the same operating temperature range (-40°C to 80°C).

Q: What certifications do these devices hold?

A: The Phoenix Contact 2910375 holds cUL and UL certifications. The Littelfuse SPD2-300-4P0-R holds CE, cURus, UL, and VDE certifications. Both are ROHS3 compliant.

Q: What is the difference between Type 1 and Type 2 protection?

A: The Phoenix Contact 2910375 is Type 2 protection. The Littelfuse SPD2-300-4P0-R provides both Type 1 and Type 2 protection. Type classification relates to surge protection coordination within electrical distribution systems.

Q: How do the discharge current ratings compare?

A: The Phoenix Contact 2910375 has nominal and maximum discharge current of 40 kA (8/20µS). The Littelfuse SPD2-300-4P0-R has nominal discharge current of 20 kA and maximum discharge current of 50 kA (8/20µS).
