Powersafe SLD0053 Line Drain 500A 185mm2 Crimp 22-32mm Blue Line 3 IP67

Description

Blue Line 3 drain for 500A temporary power.

The Powersafe SLD-L3-C185-M40B is a blue Line 3 line drain connector for single pole, high-current power runs. It terminates 185mm² cable with a crimp contact, and its locking Powerlock-compatible coupling keeps L3 connected even when the cable is under strain.

Key Features

• Cable-mount line drain: female contact inside a male insulator
• Keyed and colour coded blue for Line 3
• 500A rating with 1000V AC operating voltage
• 185mm² crimp contact termination
• 22 - 32mm cable OD range via M40B gland
• IP67 sealed when mated, IP2X touch-safe when apart
• Silver plating on the contact, high temperature thermoplastic body
• UL94-V0 rated flame retardant construction

How This Line 3 Drain Keeps Systems Safe

Only an L3 source will fit
Powersafe assigns every conductor position a dedicated colour and key profile. The blue L3 profile on this drain lets it engage an L3 source and blocks it from L1, L2, neutral or earth, so phase order and conductor identity hold up across a full five-wire set. Once engaged, the secondary lock can only be opened with a release key, keeping the joint closed while power is flowing.

Source and drain explained
Powersafe pairs a source, fitted with a male contact and normally the live end, with a drain that receives it. This drain carries a female contact set within a male insulator. Unmated, its finger-proof IP2X construction keeps the contact out of reach.

Crimping the 185mm² contact
Crimping delivers a permanent joint on 185mm² cable, and the M40B metric gland holds cable outside diameters from 22 to 32mm with built-in strain relief. As factory-endorsed tooling for this conductor size, the supplier specifies the ME37-C die set for 130kN C-style crimp tools together with the HT131-C manual hydraulic crimp tool. Work to the Powersafe Connector Assembly Guide for each termination.

Phase 3 manufactures and assembles the Powersafe range in the United Kingdom to ISO 9001:2015, supplying the power distribution, events, military and cable assembly sectors around the globe.

Q: Is the Powersafe SLD-L3-C185-M40B interchangeable with Powerlock Line 3 drains?
A: Yes. It follows the Powerlock mating system and is cross-referenced to ITT VEAM Powerlock part NLDFT-3-BL-L-C185-M40B. The L3 key restricts it to mating with a Line 3 source.

Q: What size cable goes into this Line 3 connector?
A: 185mm² cable with an outside diameter of 22 to 32mm, matching the M40B gland's clamping range. Confirm your cable's OD sits inside that window first.

Q: How do I terminate the crimp contact?
A: With a crimp tool and die rated for 185mm², following the Powersafe Connector Assembly Guide. The ME37-C die set with the HT131-C manual hydraulic crimp tool is the supplier's factory-endorsed combination.
