Description
About the Product
The Lauritz Knudsen ST98066OOOO is a 4 Pole Spreader Terminal Accessory specifically designed for MCCBs rated up to 400A in the DU400N, DN3B, & DN3 series. This accessory enhances cable connection flexibility, improves current distribution efficiency, & supports organized panel wiring in ultra high-current electrical installations. It is particularly suitable for applications requiring complete phase & neutral connectivity, secure conductor termination, & reliable power distribution in demanding industrial & infrastructure environments.
The 4 Pole configuration incorporates a dedicated neutral terminal in addition to the three phase connections, enabling complete circuit connectivity & isolation. This is essential in systems where balanced load distribution, neutral continuity, & comprehensive electrical safety are required. The inclusion of the neutral connection supports modern power distribution systems that require full phase-plus-neutral termination capability.
Spreader terminals are engineered to expand the effective terminal connection area of the MCCB, allowing the connection of larger cross-section conductors or multiple cables per pole. This enhanced connectivity simplifies cable routing, improves installation flexibility, & accommodates high-current applications where traditional terminals may be restrictive.
By increasing the contact surface area between conductors & terminals, the accessory promotes uniform current distribution across all poles. This helps reduce connection resistance, minimize voltage drops, lower heat generation, & prevent localized hotspots, thereby improving overall electrical system performance & reliability.
The spreader terminal also contributes to better panel organization by reducing cable congestion & supporting efficient wiring layouts. Improved accessibility simplifies installation, inspection, troubleshooting, & maintenance activities, particularly in high-density switchgear & control panel applications.
Designed specifically for seamless compatibility with DU400N, DN3B, & DN3 MCCB series, the accessory can be installed quickly without requiring modifications to the breaker assembly. Its robust & durable construction ensures dependable performance under demanding industrial operating conditions.
This 4 Pole spreader terminal accessory is an ideal solution for applications requiring ultra high-current capacity, complete phase-neutral distribution, enhanced electrical safety, & flexible cable management in critical power systems.
