Introduction

This Instruction Sheet provides the component selection, cabling and interconnect information to configure

Siemens Sensitrip MCCB and SB Systems Breaker ICCBs in either a Zone Selective Interlocking (ZSI)

network or in an ACCESS communications system. Installed ICCB SB breakers without communication

capability may be field upgraded by Siemens Field Service personnel only. MCCB breakers may be field

upgraded by Siemens Field Service or the end user. Refer to Figure 1 for a diagram of the possible intercon-

nect schemes described in the following scenarios.

Referenced Components

The following components are referenced in this instruction sheet, with the latest versions obtainable through the

local Siemens sales office:

• Siemens MTZ (Multiplexer Translator, Zone Interlock) [Cat. No. MTZ]  a microprocessor-based device

required for configuring and controlling a Zone Selective Interlocking (ZSI) network of up to eight (8) Sensitrip

or SB circuit breakers; multiple MTs may be interconnected for a total of 31 MTs and 248 breakers.

• Siemens MTA (Multiplexer Translator, ACCESS) [Cat. No. MTA]  a microprocessor-based device for config-

uring and controlling up to eight (8) Sensitrip MCCBs and/or SB Trip Units within an ACCESS Communica-

tions System; multiple MTs may be interconnected for a total of 31 MTs and 248 breakers. The MTA also

provides Zone Selective Interlocking capability. (Note: the SB-EC trip unit is direct ACCESS compatible but

requires an MTZ or MTA for ZSI capability)

• Siemens type EP (Expansion Plug) - an isolation device to connect Sensitrip MCCBs and SB trip units to an

MTA or MTZ. One (1) per trip unit when required.
