What kind of terminal block is this?

This is a stud connection feed-through terminal block designed for secure conductor termination using an M5 stud. It has 1 level, 2 connections and 1 potential, making it suitable for straightforward power or signal distribution where bolted conductor connections are preferred.

What conductor sizes can it accept?

It is designed for a nominal cross-section of 10 mm². The connection data includes solid conductors from 0.5 mm² to 10 mm², flexible conductors from 0.1 mm² to 10 mm², and flexible conductors with ferrules from 0.5 mm² to 10 mm². The AWG range is 26 to 8.

What voltage and current ratings does it have?

Under IEC data, the terminal block is rated at 800 V nominal voltage and 57 A nominal current when used with a 10 mm² conductor. Under UL and cUL recognition data, it is listed at 600 V and 45 A.

What mounting options are available?

It can be mounted on standardised DIN rails including NS 32 and NS 35 formats, and it can also be fitted directly in distribution boxes. This gives added flexibility for panel and enclosure layouts.

What stud size and tightening torque are required?

The connection uses an M5 stud. The specified tightening torque is 2 Nm minimum and 2.2 Nm maximum, helping achieve a secure electrical and mechanical connection.

Can it be used with ring or fork cable lugs?

Yes. It is intended for stud-based termination and is suitable for ring and fork-style cable lug connections to the relevant DIN standards. The minimum eye diameter is 5.3 mm, the maximum cable lug width is 10 mm, and the stud diameter is 5 mm.

What are the overall dimensions?

The terminal block is 13 mm wide, 53.3 mm long and has a pitch of 13 mm. Height depends on the rail used: 47 mm on NS 35/7.5, 54.5 mm on NS 35/15 and 52 mm on NS 32.

What is the housing material and colour?

It has a grey insulating housing made from PA material. The insulation material has a UL 94 V0 flammability classification.

Is it suitable for demanding environments with vibration or shock?

Yes. The product data shows passed vibration and shock testing to DIN EN 50155, including testing across the X, Y and Z axes. This makes it a good choice for installations exposed to mechanical stress and movement.

Does it offer any bridging options for potential distribution?

Yes. The design includes a bridge entry for potential distribution using standard screw bridges, and it is also described as suitable for switchable cross-connections with an insulated bridge arrangement.

Which approvals and compliance marks are listed?

The listed approvals include UL Recognized, cUL Recognized, cULus Recognized and EAC. The environmental data also states China RoHS compliance, with no hazardous substances above threshold values.

What fire and railway-related performance data is available?

The terminal block is described with UL 94 V0 flammability performance and includes railway fire performance references such as DIN EN 45545-2 for R22, R23, R24 and R26 at HL1 to HL3. Phoenix Contact 3058059 is also listed with additional rail-related fire test data including NFPA 130 and DIN 5510-2 references.
