Description

The Next Generation Power Distribution Block (PDB). Mersen power distribution blocks provide a safe and easy method of splicing cables, splitting primary power into secondary circuits and fulfilling requirements for fixed junction tap-off points. All blocks are UL and CSA approved while meeting spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®. PDB options include single or dual conductor primary inputs and up to 30 secondary outputs. Specialty blocks are available allowing for up to 7 primary inputs. The MPDB series is offered in three size categories: miniature (MPDB62 and MPDB63 series), intermediate (MPDB66 and MPDB67 series), and large (MPDB68 and MPDB69 series), in both aluminum and copper.

Features

Featuring 1 primary input opening and 4 secondary load openings per pole, this 3-pole miniature block allows commercial electricians and panel builders to seamlessly splice cables or feed up to four separate loads from a single primary line. This compact architecture optimizes space inside dense control panels while drastically simplifying distribution wiring.
The high-conductivity, tin-plated aluminum connectors are fully engineered to prevent galvanic corrosion when mating dissimilar metals. It delivers a robust ampacity rating of up to 175A for copper conductors and 135A for aluminum conductors, giving you maximum field flexibility when adapting to varying jobsite material specifications.
With an upgraded insulation rating of 1000V, this block easily handles demanding commercial HVAC systems, complex industrial automation machinery, and modern solar photovoltaic grid configurations. This elevated threshold future-proofs your control system against voltage sags and spikes while outperforming standard 600V alternatives.
When paired with properly sized Mersen Class J, T, or CC fuses, this robust block achieves a verified standalone 100 kA SCCR. This extreme level of overcurrent protection prevents destructive catastrophic panel failure during a short circuit, allowing your entire industrial enclosure to easily comply with stringent UL 508A safety mandates.
