1433294

Overview

The Phoenix Contact model 1433294 is a COMBICON SP 4/12 terminal plug designed for industrial control cabinet wiring. It features twelve positions with a 6.2 mm pitch and utilizes pull-back spring connection technology for secure wire attachment. The component supports rigid conductors from 0.08 mm² to 6 mm² and flexible conductors up to 4 mm², with a recommended nominal cross-section of 4 mm². Rated at 800 V and 32 A, it complies with IEC 61984 standards for load-free connection. The unit measures 74.4 mm in width and 21 mm in height, constructed from gray PA insulation material rated UL 94 V0.

Feature Summary

• Pull-back spring connection mechanism enables tool-free wire termination and secure contact retention without screw tightening.
• Compliant with IEC 61984 standard, allowing safe connection and disconnection under no-load or no-voltage conditions.
• Constructed from flame-retardant polyamide (PA) insulation material meeting UL 94 V0 safety requirements.
• Designed for overvoltage category III and pollution degree 3 environments within industrial control applications.

Applications

• Interfacing field sensors and actuators with PLC input/output modules
• Connecting power distribution terminals to control circuit breakers
• Wiring junction boxes for industrial automation machinery
• Signal transmission links in process control systems

Procurement Notes

Verify the specific ordering code against official Phoenix Contact catalogs to ensure compatibility with mating base units. Confirm that the application environment respects the specified voltage and current ratings. Check for required accessory items such as marking sleeves or intermediate pieces if dense mounting configurations are planned. Ensure compliance with local electrical safety regulations regarding load-free switching operations.

Selection Notes

Select this component when twelve-channel connectivity is required with a 6.2 mm pitch. Choose based on the need for spring-cage termination to reduce assembly time compared to screw connections. Consider the 800 V rating for higher voltage industrial circuits. Evaluate the 32 A current capacity against the total load of connected wires. Verify physical space constraints against the 74.4 mm width dimension.

Part Context

This terminal plug belongs to the Phoenix Contact COMBICON SP series, a standardized line of connector elements for control cabinet construction. The series provides modular solutions for signal and power distribution. The SP designation indicates a specific housing size and pin configuration optimized for DIN rail mounting bases. This component integrates into larger assemblies using standardized mounting rails and base connectors.

Replacement Considerations

Consult Phoenix Contact cross-reference tools for direct equivalents. No alternative manufacturer part numbers are verified in the provided documentation. Generic substitutes may not match the IEC 61984 load-free switching capability or the specific spring tension characteristics.
